You can enable Global Navigation Satellite System (GLONASS), which is a Russian satellite system, to increase the number of satellites available to you. When the system is used in situations with poor sky visibility, such as areas with tall buildings, this configuration can be used in combination with GPS to provide more accurate position information.

You can enable Wide Area Augmentation System (WAAS) in North America, which can provide more accurate GPS position information. When using WAAS, the device may take longer to acquire satellites.
